Abstract

Batik is a historical heritage that can still be preserved and conserved to this day. One of the types of synthetic dyes used in batik coloring is indigosol dye. Indigosol dye is a type of water-soluble dye substance. To achieve optimal sunlight exposure, technology is needed in the form of a device that can assist in the drying process to optimize the drying results and anticipate rain. One of the technologies that can assist the industrial sector in the drying process of fabrics using indigosol is an automatic dryer. This device releases wet fabric when the weather is hot and clear, and it secures the fabric when the weather is cloudy and rain is expected or when rain suddenly falls. The use of PID control on the DC motor driving this device is used to gradually increase the speed before the first two seconds so that the hung fabric does not sway too much and burden the motor. PID control is also used to ensure a stable motor rotation before the first two seconds. This research involves several testing stages, including testing the system's response with PID control and sensor readings. Testing begins with determining the PID parameter values to be used and continues by observing the system's response to the motor values controlled by PID. Sensor readings are used to determine whether the sensor is functioning properly, and this is done by reading the sensors in the Arduino IDE application. The testing process yielded the PID parameter values: KP = 0.1 , Ki = 0.01 , Kd = 0.04. The system's response with these parameter values showed stable system performance with a delay time of 1.6 seconds, rise time of 1.6 seconds, peak time of 2 seconds, no overshoot, and a settling time of 2 seconds. Keywords: Batik, Indigosol Dye, DC Motor, PID, System Response

Abstract

Batik is a historical legacy that serves as a cultural heritage and a tourism commodity for the indigenous people of Indonesia. One of the synthetic dyes that can be utilized is the dye known as indigosol. Indigosol belongs to the group of oxidation dyes, where the color emerges after undergoing oxidation processes using oxidizers such as strong acids (HCl, H2SO4), with additional nitrite as a catalyst. To achieve an even and stronger color, optimal sunlight is required so that molecules can be excited perfectly. To attain optimal sunlight, a technology in the form of an automatic drying device is necessary to aid in the drying process. This helps optimize the drying results and anticipate rain. The device is equipped with UV lamps, an Arduino Uno microcontroller, a Light Dependent Resistor (LDR) sensor, a Raindrop sensor, and an Ultrasonic sensor (HCSR). The system of this device also employs logic that combines inputs from sensors and the microcontroller with outputs such as a DC motor and UV lamp, utilizing Fuzzy Mamdani logic. Fuzzy Mamdani logic is chosen due to its simplicity and ease of understanding compared to other fuzzy logics. Fuzzy Mamdani provides 5 membership sets for the LDR sensor and 3 membership sets for the Raindrop sensor, resulting in 1 output indicating the direction of the DC motor rotation. The use of this device significantly impacts the color output of indigosol-dyed batik fabric, especially during cloudy and rainy conditions, thanks to the UV lamp serving as a substitute for sunlight. The contribution of this device is quantifiable through the use of a histogram of images, depicting changes in color density in detail. Therefore, this device not only serves as a practical solution but also delivers a positive impact on the final outcomes in the Indonesian batik industry. Keywords: Fuzzy Mamdani, Indigosol Batik, Automatic Dryer, Ultrasonic Sensor, Raindrop Sensor, LDR Sensor

Abstract

Railway is one of the ground transportation modes that has characteristics and advantages more efficient compared to other ground transportation modes. However, accidents at railway crossings remain a serious issue. To reduce accidents between trains and road users at level crossings due to negligence or errors in the system, or due to road users' lack of discipline, there is a need for automatic crossing barriers, such as the use of automatic railway crossing gates integrated with components, making it safer and minimizing the possibility of road users attempting to pass through railway gates when they are closing. This research employs arduino UNO components, HC-SR04 ultrasonic sensors, FC-51 infrared sensors, DC motors, L2986N motor drivers, 16x2 LCD with I2C module, LEDs, power supply, and an emergency stop. The railway crossing gate system is designed with a working principle using sensors to detect trains and objects around the crossing. Testing of the ultrasonic sensor successfully detected trains at a maximum distance of 5 cm, with angles of 20° and 30° providing optimal initial detection. The infrared sensor showed rapid response to approaching objects, and using PWM duty cycle 27,4% provided optimal performance for the gate's sliding movement. Additionally, testing of the LED, LCD, buzzer, and emergency stop button functioned according to their purposes. The overall testing results of the system concluded that the design of the railway crossing gate system was successfully integrated to enhance safety at railway crossings and optimize train operations.

Abstract

Health problems in Indonesia are still a concern due to the large number of deaths due to cross-infection diseases. In dentistry, the risk of cross infection often occurs because the use of dental instruments that are exposed to saliva is less than optimal in the sterilization process. Currently, the most frequently used sterilization tool in dentistry is the autoclave. Routine autoclave sterilization is usually operated at a steam pressure of 15 lb/in2. At this pressure, the temperature becomes 121oC. the time required at this temperature is 15-20 minutes (Volk and Wheeler, 1993). However, autoclaves are considered less effective because they have several disadvantages, such as being expensive, using high power, and requiring a lot of time to use. Therefore, it is necessary to have a solution to overcome the above problems. A research was carried out on designing a sterilization system for dental instruments using the ionizer method in order to determine the level of efficiency of this method in the process of sterilizing dental instruments. This sterilizer utilizes high voltage in the ion generator circuit to produce ions. This research was carried out by testing the working components and using an oscilloscope to determine the working parameters produced in the ionization circuit as well as testing in the microbiology laboratory to determine the effectiveness of the system in decontaminating bacteria. The results of this research are that the DHT22 sensor has an accuracy of 99.71% in detecting the temperature of the sterilization room and it was found that within an ion irradiation time of 300 seconds the number of bacteria was reduced by 97.32%.

Abstract

Waste incineration is one of the solutions to reduce the amount of waste. This combustion can be useful for breaking down solid waste, but the process of burning waste can produce harmful residual gas emissions. So in this study, a trial was conducted using incinerator technology, an incinerator is a device that functions to burn garbage or waste in solid form and is operated by utilizing combustion technology at a certain temperature. This research was conducted to present a solution by measuring and filteringthe remnants of waste combustion gas emissions which are very dangerous for the human respiratory system. From the description of these problems, a tool is needed that can measure and filter the remnants of waste combustion emission gas. So one way that can be done is by monitoring how bad the levels of CO and CO2 gas contained in the remaining combustion and then binding or filtering these gases using precipitator technology so that the air that will come out of the remains of dangerous combustion that can disturb humans can be reduced. Keywords: Waste incineration, incinerators, precipitators, CO gas, and CO2 gas.

Abstract

Hydroponic cultivation is a cultivation technique that utilizes water as a growing medium. The advantages of hydroponic techniques include a low possibility of pest attacks, efficient land use, soilless plant growth, increased quantity and quality of production, and better cleanliness compared to conventional agriculture. In hydroponic cultivation, important aspects to be considered are the availability of water, water temperature, and the Total Dissolved Solids (TDS) level in the nutrient solution flowing through the plant roots. In practice, manual monitoring of water availability, water temperature, and TDS levels in the nutrient solution in hydroponic tanks becomes an issue for farmers at Happy Tani farm. Manual data monitoring leads to irregular data recording, hindering the maximization of hydroponic system productivity. To address this issue, a study was conducted to design an Internet of Things-based monitoring system capable of detecting water temperature, water level, and TDS levels in hydroponic tanks. This system involves DS18B20 sensors for detecting water temperature, Ultrasonic AJ-SR04M sensors for detecting water level, and DFRobot Gravity TDS sensors for detecting TDS levels in the nutrient solution. The system can provide real-time measurement data and tank condition alerts to farmers through an Android application or website connected to the internet. The system also features datalogging on a Google Spreadsheet website for storing measurement data at regular intervals. The research involved system design, sensor testing, TDS level measurement, data transmission, and hydroponic tank condition alert systems. The results of this research indicate that the designed system is capable of transmitting data to the application and website, providing tank condition alerts, and accurate data measurement with error rates for DS18B20 sensors at 0.69%, Ultrasonic AJ-SR04M sensors at 0.5%, DFRobot Gravity TDS sensors for EC at 3.16%, and TDS at 3.37%.

Abstract

Microgreens are plants that require little harvesting time and can be grown indoors. One of the plants that can be grown withmicrogreen is sunflowers. However, growing microgreen sunflowers has problems, namely the growth of mold, and long legs.Some of the factors that affect this are temperature, humidity, and light. Microgreens can be grown indoors, but the indoorconditions are not suitable for the needs of microgreens. The average indoor temperature is 27°C, the air humidity is 80%, and itlacks light supply. Meanwhile, the ideal temperature required by sunflower microgreen is 20-25°C and the ideal humidity is 40-60%. With these conditions, an environmental control system for sunflower microgreen is needed. There are two systems made,namely the temperature and humidity control system with fuzzy logic in controlling the fan speed and the lighting system with LEDlights and lighting for 16 hours. Tests conducted show that the DHT22 sensor used has a temperature accuracy of 99.58% andhumidity accuracy of 99.97%. Testing of the entire system shows that the growth box during the day with the control systeminstalled, can reduce the temperature to an average of 23.16% and humidity of 51.63%. While at night the temperature can reach22.7% and humidity reaches 52.48%. This system can reduce the temperature and humidity to be in accordance with the needs ofmicrogreen sunflowers and fuzzy logic control system can improve the temperature drop to be more stable and close to the setpoint, which is 23°C temperature and 50% humidity.

Abstract

Due to their high nutritional content, oyster mushrooms are a valuable food source with increasing demand. However, increasing oyster mushroom production is challenging because they require specific environmental conditions and cannot grow just anywhere. Therefore, it's crucial to adjust the environmental conditions for optimal oyster mushroom cultivation. Base on the problem, there is a need for a system that can adjust environmental conditions to meet the optimal requirements for oyster mushroom cultivation. Oyster mushrooms typically thrive in highland environments. Several environmental parameters that can influence their growth include CO2 concentration (575-731 ppm), temperature (16˚C to 30˚C), and humidity (80-95%). The designed system is expected to measure these environmental parameters using sensors, include the MQ-135 sensor and the DHT22 sensor.Additionally, actuators will be used to control the environmental parameters and bring them to the desired levels, which is exhaust fan and DC pump. The use of these sensors and actuators will be integrated with an ESP32 microcontroller, which can proces and manage the system. To maximize the quality of the oyster mushrooms, the system will utilize the Internet of Things (IoT), for automated and remote monitoring and control of the oyster mushroom cultivation process through the Blynk application.
